Abstract
Wireless Sensor Networks(WSNs) have problem of energy starvation in their operations. This constraint demands that the topology of communicating nodes should be limited. One of the ways of restraining the communicating nodes is by creating a Connected Dominating Set(CDS) of nodes out of them. In this paper, an Optimized Region Based Efficient Data(AORED) routing protocol for WSNs has been proposed. CDS has been employed in AORED to create a virtual backbone of communicating nodes in the network. The empirical study involving extensive simulations show that the proposed routing protocol outperforms the legacy DEEC and SEP protocols. AORED has increased number of transmission rounds, increased number of clusterheads and reduced number of packets sent to the basestation as compared to DEEC and SEP protocols.

Summary
Wireless sensor networks (WSNs) have grabbed attention of researchers in recent years due to their wide range of applications and potential use. Cheap and small sized sensor nodes cannot be equipped with a large battery source. As these sensors have limited energy, it restricts the sensors to use limited memory, limited transmission power and perform limited computations to increase the lifetime of sensor. Active state uses the maximum amount of resources available to the nodes which results in energy consumption. The only task done by the nodes is of sensing without receiving or transferring the data. Sleep mode consumes the minimum amount of energy as compared to active and idle mode Another way to conserve nodes’ energy is to use energy efficient routing protocols and use limited transmit power if possible that reduces transmission range.
